Wireless LAN Network
This chapter provides background information on wireless LAN network.
2.1 Overview
This section describes the wireless LAN network terms and applications.
2.1.1 SSID
The SSID (Service Set Identity) is a unique name shared among all wireless devices in a wireless network.
Wireless devices must have the same SSID to communicate with each other.
Wireless devices must have the same SSID to communicate with each other.
2.1.2 Channel
A radio frequency used by a wireless device is called a channel.
2.1.3 Transmission Rate (Transfer Rate)
The ZyXEL G-162 provides various transmission (data) rate options for you to select. Options include
Fully Auto, 1 Mbps, 2 Mbps, 5.5 Mbps, 11 Mbps, 6 Mbps, 9 Mbps, 12 Mbps, 18 Mbps, 22 Mbps, 24
Mbps, 36 Mbps, 48 Mbps, 54 Mbps and 125 Mbps. In most networking scenarios, the factory default
Fully Auto setting proves the most efficient. This setting allows your ZyXEL G-162 to operate at the
maximum transmission (data) rate. When the communication quality drops below a certain level, the
ZyXEL G-162 automatically switches to a lower transmission (data) rate. Transmission at lower data
speeds is usually more reliable. However, when the communication quality improves again, the ZyXEL G-
162 gradually increases the transmission (data) rate again until it reaches the highest available transmission
rate.
You can select any of the above options. If you wish to balance speed versus reliability, select 54 Mbps in
a networking environment where you are certain that all wireless devices can communicate at the highest
transmission (data) rate. 1 Mbps or 2 Mbps are used often in networking environments where the range of
the wireless connection is more important than speed.
